Question

F(x) = x3

If x = −2, y =


If x = −1, y =


If x = 0, y =

Answer 1

`If\: x = 0, y = 0`

`If\: x = -1, y = -1`

`If\: x = -2, y = -8`

Explanation:

`0 = {0}^(3) \\ -1 = {-1}^(3) \: or \: [-1]^(3) \\ -8 = {-2}^(3) \: or \: [-2]^(3)`

I am joyous to assist you anytime.

Answer 2

Answer: If x = −2, y =-8 ; If x = −1, y =-1 ; If x = 0, y =0

Explanation:

Hi, to obtain the values of the variable y in each case, we have to replace the variable x for the value given and solve.

So;

f(x) = x3

f(-2) = (-2)³= -8

f(-1) = (-1)³= -1

f(0) = (0)³=0

In conclusion, If x = −2, y =-8 ; If x = −1, y =-1 ; If x = 0, y =0.
